TRAL AND SOUTHERN PORTION, 1908-10. 



INTRODUCTION. 



Authority for Investigations: 

This volume contains the results of flow measurements on certain 
streams in the State of Illinois. The work was performed by the water- 
resources branch of the United States Geological Survey, M. 0. Leigliton,. 
hydrographer, in cooperation with the Internal Improvement Commis- 
sion of Illinois, Isham Eandolph, chairman. The Internal Improvement 
Commission paid for all the fleld work; the cost of the office computa- 
tions was borne by the Commission and the Survey. The Geological 
Survey also furnished all instruments and supervised and directed the 
work. The authority for this expenditure is contained in the organic 
law of the Internal Improvement Commission (Session Laws, Forty- 
fifth General Assembly, Adjourned Session, p. 33), which provides, 
among other things, as follows : 

"The duties of the Commission shall be to investigate * * * the re- 
clamation of lands subject to overflow or inundation, * ' * * and such 
other statistics and data as will enable the next General Assembly to properly 
formulate and devise ways and means whereby legislative enactment may 
be had to carry out and put into effect the benefits to be derived by the 
* * * reclamation of lands subject to inundation in Illinois." 

Inasmuch as the study of run-off is the first consideration in connec- 
tion with drainage projects and because the estal)lishment of the height 
and distance between levees which are designed to control the entire 
flood flow of a stream involves the determination of the volume of water 
that will come down the valley, these investigations are well within the 
authority of the law. 

The work has been supported since the fiscal year ending June 30, 
1909, from funds provided in the Omnibus Appropriation Act of the 
Forty-sixth General Assembly passed June 3, 1909, and entitled: 

"An Act to provide for the ordinary and contingent expenses of the State 
Government until the expiration of the fiscal quarter after the adjournment 
of the next regular session of the General Assembly." 

Section 70 of this Act appropriates "to the Internal Improvement 
Commission * * * -^qp g^^'vey of rivers and study of water supply 
and all other necesvsarv expenses for the work of the Commission the 
sum of $30,000.00." 



Scope of Investigation: 

These investigations are not complete nor do they include all the river 
system or parts thereof that might purposefully be studied. The scope 
of the work is limited to that which can be provided with the appropria- 
tions available. The field covered and the character of the work are 
believed to be the best that could be accomplished under the controlling 
conditions. 

The investigations have been concentrated upon streams in the central 
and southern portion of the State where water supply, prevention of 
overflow and reclamation of swamp land make the strongest appeal for 
immediate study of the problems. 

It is essential that records of stream flow shall be maintained during 
a period of years sufficient to cover all stages, in order that within reason- 
able limits the entire range of flow from the absolute maximum to the 
absolute minimum may be determined. The length of such a period 
manifestly varies for different streams and cannot be absolutely deter- 
mined. Experience has shown that the records should cover from five 
to ten years, or for some streams twenty years or more, the limit being 
determined by the relative importance of the stream and the inter- 
dependence of the results and other long-time records on adjacent 
streams. 

The records herein set forth cover a period of over two years and 
indicate a fairly completed range of flow from maximum to minimum. 
The gauging stations are being maintained under the present appropria- 
tion and the records will be kept as long as the General Assembly sees 
fit to appropriate funds for the purpose. 

In all engineering work there is a point of refinement beyond which 
it is needless and wasteful to proceed, and this principle applies with 
especial force to stream-flow measurements. It is confidently believed 
that with some unavoidable exceptions the stream-flow data presented 
in this publication are sufficiently accurate for all practical purposes. 

It must be borne in mind, however, that these records extend over a 
comparatively short period of time and all ])ersons are cautioned to use 
the greatest care in the utilization of sncli in('oni])lete records. 

]*urj)()s('H of the "lVo7'/i'; 

Among the purposes for which the results contained in this volume 
are requisite are navigation, domestic water supply, water power, swamp 
and overflow land drainage, and flood prevention. The demands of all 
these interests are iniincdiate. 

Navigation : 

At the general election of Xov. 3, 1008, the Constitution was amended 
by popular vote, and the General Assembly was authorized to issue twenty 
million dollars in bonds for the construction of a waterway from Joliet, 
111., to IJtica, 111. The further extension of this waterway to the Gulf 
is under consideration by Congress and there is already an eight-foot 



navigation below Utica. With the completion of tlie Lockport-Utica 
link in this waterway there will be opened up through the heart of the 
State and along its western border 550 miles of navigable trunk line 
waterwa3^ There are also about 125 miles of navigable waterway on the 
Ohio river along the southern boundary, and the Wabash is navigable 
along the eastern border. When the State and federal governments 
become committed to a definite policy of inland waterway improvements 
the development of the tributaries to these trunk waterways become of 
paramount importance. It is obvious that the determination of stream- 
flow is necessary to the intelligent solution of the many problems 
involved. 

Domestic ^yater Supphj : 

The highest use of water is that of domestic supply, and while the 
State interest in this aspect of the matter is less direct than in the 
aspects already named, this use of water nevertheless has so broad a 
significance with respect to the general welfare that the State govern- 
ment is ultimately and intimately concerned. 

^yatc'r Power: 

The time is rapidly approaching when the development of the water 
power of the country will be an economic necessity. Our stock of coal 
is being rapidly depleted and the cost of steam power is increasing 
accordingly. Industry will cease its growth if cheap power is not 
available. Water power is the only avenue now open. When the electric 
transmission of power was accomplished the relation of our water powers 
to economic conditions changed entirely. Previous to the day of electric 
transmission the importance of a water power was largely confined to 
the locality at which it was generated, but it has now become a public 
utility in which the individual citizen is vitally interested. 

There is a great paucity of accurate observation as to the amount of 
water power available within the State, and inasmuch as the amount of 
water power that may be made available is dependent on the flow of 
rivers, the investigation of flow becomes a prerequisite in the judicial 
management of this source of energy. 

There are practically no water power sites on any of the streams that 
have been studied up to the date of this report, and studies and investi- 
gations should be extended to cover those streams upon which tliere 
are opportunities for the development of water power. 

Drainage of Swamp and Overfloiued Lands: 

There are approximately 3,000 square miles of land subject to overflow 
along our intra-state streams. Probably 90 per cent of the bottom lands 
of the State are unprotected or inadequately protected against floods and 
it is estimated that if they could all be brought under successful cultiva- 



8 

tion there would be added to the farm value of the State over one hundred 
million dollars. There would also be additional benefits to be derived 
from improved health conditions. 

The study of run-oS is the first consideration in connection with 
drainage projects. If, by the drainage of a large area into any particular 
channel, that channel becomes so gorged wdth water which it had not 
hitherto been called upon to convey, that overflow conditions are created 
in places where previously the land was not subject to inundation, then 
drainage results merely in an exchange of land values. This is not the 
purpose of drainage improvement. By making use of the data in this 
report such a contingency as mentioned above would be avoided. 

Flood Prevention : 

The damage from floods to property and crops in the Illinois bottoms 
is enormous. Xo careful estimate of the monetary loss has been made, 
owing to the absence of comprehensive data, but these losses are not 
merely local in effect. They constitute an annual tax on the property 
in large areas of the State which should be reduced in the orderly prog- 
ress of government. 

It goes without saying that any consideration of flood prevention must 
be based on a thorough knowledge of stream-fiow, both in the contribut- 
ing areas which furnish the water and along the lowland rivers. 



Publications: 

The data on stream-flow collected by the Illinois cooperation appears 
here in print for the first time, and the records of most of the stations 
discussed in this report extend over a period of more than two years. 

The order of treatment of stations in each basin in these papers is 
downstream. Tlie main stream of any river is determined on the basis 
■of drainage area. After all stations from the source to the mouth of the 
main stem of the river have been given, the tributaries are taken up in 
regular order from source to mouth. The tributaries are treated the 
same as the main stream, all stations in each tributary basin being given 
before taking up the next one below. 

The studies and investigations of stream flow in the State of Illinois 
will be continued until the appropriation for the current fiscal quarter 
is exhausted. Their further continuance and publication being dependent 
upon further appropriation and authority. 

Definiiion of Terms: 

''Hie volume of water flowing in a stream — the "run-of¥" or "dis- 
charge" — is expressed in various terms, each of which has become 
associated with a certain class of work. These terms may be divided 
into two groups: (1) Those which represent a rate of flow, as second- 
feet, gallons per minute, miner's inches, and run-off in second-feet per 



9 

square mile, and {2} those whieli re])i'c'r«(_'iit ilie actual quantity of water, 
as run-otl: in depth in inches and acre-feet. They may be defined as 
follows : 

"Second-foot" is an abbreviation for cubic foot per second and is the rate 
of discharge of water flowing in a stream 1 foot v/ide, 1 foot deep, at a 
rate of 1 foot per second. It is generally used as a fundamental unit from 
which others are computed by the use of the factors given in the following 
table of equivalents. 

"Gallons per minute" is generally used in connection with pumping and 
city water supply. 

The "miner's inch" is the rate of discharge of water that passes through 
an orifice 1 inch square under a head which varies locally. It is commonly 
used by miners and irrigators throughout the West and is defined by statute 
in each state in which it is used. 

"Second-feet per square mile" is the average number of cubic feet of water 
flowing per second from each square mile of area drained, on the assump- 
tion that the run-off is distributed uniformly both as regards time and area. 

"Run-off in inches" is the depth to which the drainage area would be 
covered if all the v/ater flowing from it in a given period were conserved and 
uniformly distributed on the surface. It is used for comparing run-off with 
rainfall, which is usually expressed in depth in inches. 

"Acre-foot" is equivalent to 43,560 cubic feet, and is the quantity required 
to cover an acre to the depth of 1 foot. It is commonly used in connection 
with storage for irrigation work.

Xo discharge table was made for any of these latter stations for 
reasons given in tlie description of the tables. 

In addition to statements regarding the location and instaUation of 
cnrrent-meter stations, the descriptions give information in regard to 
any conditions which may affect the constancy of the relation of gage 
lieight to discharge, covering such points as ice, shifting conditions of 
How, and backwater; also, full information regarding diversions which 
decrease the total flow at the measuring section. Statements are also 
made regarding the accuracy and reliability of the data. 

The discharge-measurement table gives the results of the discharge 
measurements made during the year, including the date, name of hydro- 
grapher, width and area of cross section, gage height and discharge in 
second-feet. 

The table of dail}- gage heights gives the daily fluctuations of the 
surface of the river as found from the gage readings taken each day. 
At most stations the gage is read once per day, either in the morning 
or in the evening. The gage height given in the table represents the 
elevation of the surface of the water above the zero of the gage. All 
gage heights during ice conditions, backwater from obstructions, etc., 
are published as recorded, with suitable foot notes. The rating is not 
applicable for such periods unless the proper correction to the gage 
heights is known and applied. Attention is called to the fact that the 
zero of the gage is placed at an arbitrary datum and has no relation to 
zero flow or the bottom of the river. In general, the zero is located some- 
what ])elow the lowest known flow, so that negative readings shall not 
occur. 

The discharge measurements and gage heights are the base data from 
which the rating tables and monthly discharge taldes are computed. 

The rating table gives either directly or by interpolation the discharge 
in second-feet, corresponding to every stage of the river recorded during 
the period for which it is applicable. 

In the table of monthly discharge the column headed ''^raximum'' 
gives the mean flow, as determined from the rating tal)le, for the day 
M'hen the mean gage height was highest. As the gage height is the mean 
for the day, it does not indicate correctly the period when the water sur- 
face was at crest height and the corresponding discharge consequently 
larger than given in this column. Likewise, in the column of "^linimum" 
the quantity given is the mean flow for the day when the mean gage 
height was lowest. The column headed "Mean'^ is the average flow in 
cubic feet for each second during the month. On this the conijnitations 
for the remaining columns, whicli are defined on page T, are based. 

In tlie t^^bles of climatological data ^appendix) are given, for each of 
the stations in the three sections of Illinois, designated as sections 64, 
65 and G6 of the Climatological Division of the Weather Bureau of the 



12 

Department of Agriculture; the precipitation, monthly, annual and 
average amounts (in inches and hundreds) ; the average number of days 
with .01 inch or more of precipitation; the average snowfall; the mean 
temperature ; the lowest temperature ; prevailing wind direction ; highest 
temperature ; mean relative humidity ; average hourly wind movement 
(in miles) ; frost data, monthly and annual mean precipitation for the 
year 1909, with departures from the normal; monthly and annual 
mean temperature for the year 1909, with departures from the normal; 
monthly maximum temperatures for the year 1909, with dates ; monthly 
minimum temperature for the year 1909, with dates, and a list of the 
cooperative observers for each station in the three sections. 

Field Methods of Measuring Stream Floic : 

There are three distinct methods of determining the flow of open- 
channel streams: (1) by measurements of slope and cross section and 
the use of Chezy's and Kutter's formulas; (2) by means of a weir or 
dam; (3) by measurements of the velocity of the current and of the 
area of the cross section. The method chosen depends on the local 
physical conditions, the degree of accuracy desired, the funds available 
and the length of time that the record is to be continued. The velocity 
method has been used exclusively in these determinations and a de- 
scription of this method is therefore considered sufficient. 

Velocity Method: 

Streams in general present throughout their courses to a greater or 
less extent all conditions of permanent, semi-permanent and varying 
conditions of flow. In accordance with the location of the measuring 
section with respect to these physical conditions, current-meter gaging 
stations may in general be divided into four classes: (1) those with per- 
manent conditions of flow; (2) those with beds which change only during 
extreme high water; (3) those with beds Avhich change frequently, but 
which do not cause a variation of more than about 5 per cent of the 
discharge curves from year to year, and (4) those with constantly sliift- 
ing beds. In determining tlie daily flow, different office methods are 
necessary for each class. Tlic fleld data on which the determinations 
arc based and the metliods of collecting them are, however, in general 
the same. 

Great care is taken in the selection and equipment of gaging stations 
for (Ictormining discharge by velocity measurements, in order that the 
data may liave tlie required degree of accuracy. They are located as 
far as possible, at sucli ])oints tliat the relation between gage height and 
discharge will always remain constant for any given stage. The ex- 
perienc(^ of engineers of the geological survey has been that permanency 
of conditions of flow is the prime requisite of any current-meter gaging 
station when maintained for several years, unless funds are available 
to cover all changes in conditions of flow. A straight, smooth section, 
without cross cnrrents, backwater, boils, etc., at any stage, is highly de- 
sirable; but on most streams it is not attainable, except at the cost of 



13 

a cable Gquipment. Eoiigh perinanont sections, if measiireineiit.- are 
properly made by experienced engineers, taking measuring points at a 
distance apart of 2 to 5 jDcr cent, or less, of a total width, will, within 
reasonable limits, yield better results for a given outlay of money than 
semi-permanent or shifting sections with smooth, uniform current. So 
far as possible, stations are located where the banks are high and not 
subject to overflow at high stages, and out of the influence of tributary 
streams, dams, or other artificial obstructions which might affect the 
relation between gage height and discharge. 

A gaging station consists essentially of a gage for determining the 
daily fluctuations of stage of the river and some structure or apparatus 
from which discharge measurements are made, usually a bridge or 
cable. 

The two factors required to determine the discharge of a stream past 
a section perpendicular to the mean direction of the current are the 
area of the cross section and the mean velocity of flow normal to that 
section. 

In making a measurement with a current meter a number of points, 
called measuring points, are measured off above and in the plane of the 
measuring section at which observations of depth and velocity are taken. 
These points are spaced equally for those parts of the section where the 
flow is uniform and smooth and are spaced unequally for other parts, 
according to the discretion and judgment of the engineer. In general, 
the points should not be spaced farther apart than 5 per cent of the 
distance between piers, nor farther apart than the approximate mean 
depth of the section at the time of measurement. 

The measuring points divide the total cross section into elementary 
strips, at each end of which observations of depth and velocity are made. 
The discharge of any elementary strip is the product of the average of 
the depths at the two ends times the width of the strip times the average 
of the mean velocities at the two ends of the strip. The sum of the dis- 
charges of the elementary strips is the total discharge of the stream. 
(For a discussion of methods of computing the discharge of a stream, 
see Engineering Xews, June 25, 1908.) 

Depths for the determination of the area are usually obtained by 
sounding with the current meter and cable. In rough sections or swift 
current, an ordinary weight and cable are used, particular care being 
taken that all observations shall be in the plane of the cross section. 

Two methods of determining the velocity of flow of a stream are in 
general use — the float method and the current-meter method. 

The float method, with its various modifications of surface, sub- 
surface and tube or rod floats, is now considered obsolete in the ordinary 
practice of the United States Geological Survey. The use of this method 
is limited to special conditions where it is impracticable to use the cur- 
rent meter, such as in places where large quantities of ice or debris which 
may damage the meter are flowing with the current, and for miscellane- 
ous measurements or other work where a high degree of accuracy is not 
necessary. Tube floats are very satisfactory for use in canals with 
regular bottoms and even flow of current. Measurements by the float 
method are made as follows : The velocitv of flow of the stream is 



14 

obtained by observing the time which it takes floats set free at different 
points across the stream to pass between two range lines about 200 feet 
apart. Tlie area nsed is the mean vahie obtained from several cross sec- 
tions measured between tlie two range lines. The chief disadvantages of 
this method are difficulty in obtaining the correct value of mean area 
for the course used and uncertainty regarding the proper coefficient 
to apply to the observed velocity. 

The Price current meter is now used almost to the exclusion of other 
types of meters by the United States Geological Survey in the determin- 
ation of the velocity of flow of water in open channels, a use for which 
it is adapted under practically all conditions. Briefly, the meter con- 
sists of six cups attached to a vertical shaft which revolves on a conical 
hardened steel point when immersed in moving water. The revolu- 
tions are indicated electrically. The rating, or relation between the 
velocity of the moving water and the revolutions of the wheel, is de- 
termined for each meter by drawing it through still water for a given 
distance at different speeds and noting the ]unnl)er of revolutions lor 
each run. 

From these data a rating table is prepared wliicli gives the velocity per 
second of moving water for any number of revolutions in a given time 
interval. The ratio of revolutions per second to velocity of flow in feet 
per second is very nearly a constant for all s])eeds and is approxi- 
mately 0.45. 

Three classes of methods of measuring velocity with current meters 
are in general use — multiple-point, single-point, and integration. 

The two ])rinci})al multiple-point methods in general use are the 
vertical curve and 0.2 and 0.8 depth. 

In the vertical velocity curve method a series of velocity determiiia- 
tions are made in each vertical at regular intervals, usually about 10 
to 20 per cent of the depth apart. By plotting these velocities as ab- 
scissas and their depths as ordinates and drawing a smooth curve among 
the resulting points, the vertical velocity curve is developed. This curve 
shows grai)hically the magnitude and changes in velocity from the sur- 
face to the bottom of the stream. The mean velocity in the vertical is 
then obtained by dividing the area bounded by this velocity curve and 
its axis by the depth. This method of obtaining the mean velocity in 
the vertical is ])r()l)al)ly the best known, but on account of the length 
of time ref|uire(l to make a complete measurenuMit, its use is largely 
limited to the determination of coe(Tici(Mits for ])uri)oses of com])arison 
and to measurcnu'iits under ice. 

In the second mult iplc-poinl method the meter is hehl successively at 
()/! and o.S (Icpjh, nnd the menu of the velocities at these two points is 
taken as the mean Nclocily I'oi- lh;it vei'tic;il. On the nssuini)tion that 
the vei'tical velocity cur\(' is ;i common pnrahola with hoi'izontal axis, 
the mean of the velocities at (1.22 and 0.75) de|)th will give (closely) the 
mean velocity in the vertical. >\ctual observations under a wide range 
of conditions show thiit this multii)le-i)oint method gives the mean 
velocity very closely for open-w;ite!- conditions nnd that in a completed 
measui-ement it seldom \aries as much as 1 |ter cent from the \alue 



15 

given by the vertical velocity curve method. ^loreover, the indications 
are that it holds nearly as 'well for ice-covered rivers. It is very ex- 
tensively used in the regular practice of tlie Ignited States Geological 
Survey. 

The single-point method consists in holding the meter either at the 
depth of the thread of mean velocity, or at an arbitrary dei)tii for 
which the coefficient for reducing to mean velocity has been determined 
or must be assumed. 

Extensive experiments by means of vertical velocity curves show that 
tlie thread of mean velocity generally occurs between 0.5 and 0.7 total 
depth. In general practice the thread of mean velocity is considered to 
be at 0.() depth, and at this point the meter is held in most of the 
measurements made by the single-point method. A large number of 
vertical velocity curve measurements, taken on many streams and under 
varying conditions, show that the average coefficient for reducing the 
velocity obtained at O.G depth to mean velocity is ])ractically unity. The 
variation of the coefficient from unity in individual cases is, however, 
greater than in the 0.2 and 0.8 method, and the general results are not as 
satisfactory. 

In the other principal single-point method the meter is held near the 
surface, usually 1 foot below, or low enough to be out of the effect of the 
wind or other disturbing influences. This is known as the sub-surface 
method. The coefficient for reducing the velocity taken at the sub- 
surface to the mean has been found to be in general from al)out 0.85 
to 0.95, depending on the stage, velocity and channel conditions. The 
higher the stage the larger the coefficient. The method is especially 
adapted for flood measurements, or when the velocit}' is so great that tlie 
meter can not be kept in the correct position for the other methods. 

The vertical integration method consists in moving the meter at a 
slow, uniform speed from the surface to the l)ottom and back again to 
the surface and noting the number of revolutions and the time taken 
in the operation. This method has the advantages that the velocity at 
each point of the vertical is measured twice. It is useful as a check on 
the ])o\ui methods. In using the Price meter great care should be taken 
that the vertical movement of the meter is not rapid enough to vitiate the 
accuracy of the resulting velocity. 

The determination of the flow of an ice-covered stream is difficult, 
owing to diversity and instability of conditions during the winter period, 
and also to lack of definite information in regard to the laws of flow of 
water under ice. The method now employed is to make frequent dis- 
charge measurements during the frozen periods by the 0.2 and 0.8 and 
the vertical velocity curve methods, and to keep an accurate record of the 
conditions, such as the gage height to the surface of the water as it rises 
in a hole cut in the ice, and the thickness and character of the ice. 
From these data an approximate estimate of the daily flow can be made 
by constructing a rating curve (really a series of curves) similar to that 
used for open channels, 1)ut considering, in addition to gage heights and 
discharo-e. the varvina" thickness of ice. 



16 

Office Methods of Computing and Studying Discharge and Run-Off: 

At the end of each year the field or base data for current-meter gaging 
stations, consisting of daily gage heights, discharge measurements, and 
full notes, are assembled. The measurements are plotted on cross- 
section paper and rating curves are drawn wherever feasible. The 
rating tables prepared from these curves are then applied to the tables 
of daily gage heights to obtain the daily discharge and from these appli- 
cations the tables of monthly discharge and run-off are computed.. 

Kating curves are drawn and studied with special reference to the 
class of channel conditions which they represent. The discharge meas- 
urements for all classes of stations wdien plotted with gage heights in 
feet as ordinates and discharges in second-feet as abscissas define rating 
curves which are more or less generally parabolic in form. In many 
cases curves of area in square feet and mean velocity in feet per second 
are also constructed to the same scale of ordinates as the discharge curve. 
These are used mainly to extend the discharge curves beyond the limits 
of the plotted discharge measurements, and for checking purposes to 
avoid errors in the form of the discharge curve and to determine and 
eliminate erroneous measurements. 

For every published rating table the following assumptions are made 
for the period of application of the table: (a) That the discharge 
is a function of and increases gradually with the stage; (b) that the 
discharge is the same whenever the stream is at a given stage, and hence 
such changes in conditions of flow as may have occurred during the 
period of application are either compensating or negligible, except that 
the rating as stated in the footnote of each table is not applicable for 
known conditions of ice, log jams, or other similar obstructions; (c) 
that the increased and decreased discharge due to change of slope on 
rising and falling stages is either negligible or compensating. 

As already stated, the gaging stations may be divided into several 
classes, as indicated in the following paragraphs: 

The stations of Class 1 represent the most favorable conditions for an 
accurate rating and are also the most economical to maintiiin. The 
bed of the stream is usually composed of rock and is not subject to the 
de])osit of sediment and loose material. This class includes also many 
stations located in a pool below which is a permanent rocky riftle that 
controls the flow like a weir. Provided the control is sufficiently high 
and close to the gage to prevent cut and fill at the gaging point from 
materially affecting the slope of the water surface, the gage height will 
for all practical purposes be a true index of the discharge. Discharge 
measurements made at such stations usually ])lot within 2 or :> per cent 
of tlie mean-discharge curve and the rating develo]KMl from ihat curve 
represents a very high degree of accuracy. 

Class 2 is confined mainly to stations on rough mountainous str ams 
with steep slopes. The beds of such streams are, as a rule, comparati -ely 
permanent during low and medium stages, and when the flow is s iffi- 
ciently well defined by an adequate number of discharge measurements 
before and after each flood the stations of this class give nearly as good 



17 

results as those of Class 1. As it is seldom possible to make measure- 
ments covering the time of change at flood stage, the assumption is often 
made that the curves before and after the flood converged to a common 
point at the highest gage heiglit recorded during the flood. Hence the 
only uncertain period occurs during the few days of highest gage heights 
covering the period of actual change in conditions of How. 

Class 3 includes most of the current-meter gaging stations maintained 
by the United States Geological Survey. If sufficient measurements 
could be made at stations of this class, results Avould be obtained nearly 
equaling those of Class 1, but owing to the limited funds at the disposal 
of the Survey this is manifestly impossible, nor is it necessary for the 
uses to which discharge data are applied. The critical points are, as a 
rule, at relatively high or low stages. The percentage error, however, is 
greater at low stages. Xo absolute rule can be laid down for stations 
of this class. Each rating curve must be constructed mainly on the 
basis of the measurements of the current year, tlie engineer being guided 
largely by the past history of the station and the following general law : 
If all measurements ever made at a station of this class are plotted on 
cross-section paper, they will define a mean curve which may be called 
a standard curve. It has been found in practice that if, after a change 
caused by high stage, a relatively constant condition of flow occurs at 
medium and low stages, all measurements made after the change will 
plot on a smooth curve which is practically parallel to the standard 
curve with respect to their ordinates, or gage heights. This law of the 
parallelism of ratings is the fundamental basis of all ratings and esti- 
mates at stations with semi-permanent and shifting channels. It is not 
absolutely correct, but, Tvith few exceptions, answers all the practical 
requirements of estimates made at low and medium stages after a change 
at a high stage. This law appears to hold equally true whether the 
change occurs at the measuring section or at some controlling point 
below. The change is, of course, fundamentally due to change in the 
channel caused by cut, or fill, or both, at and near the measuring section. 
For all except small streams the changes in section usually occur at the 
bottom. The following simple, but typical, examples illustrate this law : 

(a) If 0.5 foot of planking were to be nailed on the bottom of a 
well-rated wooden flume of rectangular section there would result, other 
conditions of flow being equal, new curves of discharge, area, and 
velocity, each plotting 0,5 foot above the original curves when referred 
to the original gage. In other words, this condition would be analogous 
to a unifonn fill or cut in a river channel which either reduces or 
increases all three values of discharge, area, and velocity for any gage 
height. In practice, however, such ideal conditions rarely exist. 

(b) In the case of a cut or fill at the measuring section there is a 
marked tendency toAvard decrease or increase, respectively, of the velocity. 
In other words, the velocity has a compensating effect, and if the com- 
pensation is exact at all stages the discharge at a given stage will be the 
same under both the new and the old conditions. 



2 S W 



18 

(c) In the case of uniform change along the crest of a weir or roclcy 
controlling point, the area curve will remain the same as before the 
change, and it can be shown that here again the change in velocity carve 
is such that it will produce a new discharge curve essentially parallel 
to the original discharge curve with respect to their ordinates. 

Of course in actual practice such simple changes of section do not 
occur. The changes are complicated and lack uniformity, a cut at one 
place being largely offset by a fill at another and vice versa. If these 
changes are very radical and involve large percentages of the total 
area — as, for example, on small streams — there may result a wide 
departure from the law^ of parallelism of ratings. In complicated 
changes of section the corresponding changes in velocity which tend to 
produce a new^ parallel discharge curve may interfere with each other 
materially, causing eddies, boils, backwater, and radical changes in 
slope. In such extreme conditions, however, the measuring section 
would more properly fall under Class 4 and would require very frequent 
measurements of discharge. Special stress is laid on the fact that in 
the lack of other data to the contrary the utilization of this law will 
yield the most probable results. 

Slight changes at low or medium stages of an oscillating character 
are usually averaged by a mean curve drawn among them parallel to 
the standard curve, and if the individual measurements do not vary 
more than 5 per cent from the rating curve the results are considered 
good for stations of this class. 

Class 4 comprises stations that have soft, muddy, or sandy beds. Good 
results can be obtained from such sections only by frequent discharge 
measurements, the frequency varying from a measurement every two 
or three weeks to a measurement every day, according to the rate of 
diurnal change in conditions of flow. These measurements are plotted 
and a mean or standard curve drawn among them. It is assumed that 
there is a different curve for every day of the year and that this rating 
is parallel to the standard curve with respect to their ordinates. On 
the day of measurement the rating curve for that day passes through 
that measurement. For days between successive measurements it is 
assumed that the rate of change is uniform, and hence the ratings for 
the intervening days are equally spaced between the ratings passing 
through the two measurements. This method must be modified or aban- 
doned altogether under special conditions. Personal judgment and a 
knowledge of the conditions involved can alone dictate the course to 
pursue in such cases. 

The computations have, as a rule, been carried to three significant 
figures. Computation machines, Crelle's tables, and the 20-inch slide 
rule have been generally used. All computations are carefully checked. 

After the computations have been completed they are entered in tables 
and carefully studied and intercompared to eliminate or account for all 
gross errors, so far as possible. ^lissing periods are filled in, so far as 
is feasible, by means of comparison with adjacent streams. The attempt 



19 

is .made to coiuplete years or periods of discliarge, thus eiimiiiaiiiig 
fragmentary and disjointed reeords. Full notes aeeompanying such 
estimates follow the monthly discharge tables. 

For most of the stations estimates have been made of the monthly 
discharge during frozen periods. These are based on measurements 
under ice conditions wherever available, daily records of temperature 
and precipitation obtained from the United States Weather Bureau 
climate and crop reports, observers' notes of conditions, and a care- 
ful and thorough intercomparison of results with adjacent streams. 
Although every care possible is used in making these estimates they 
are often very rough, the data for some of them being so poor that 
the estimates are liable to as much as 25 to 50 per cent error. It is 
believed, however, that estimates of this character are better than none 
at all, and serve the purpose of indicating in a relative way the propor- 
tionate amount of flow during the frozen period. These estimates are, 
as a rule, included in the annual discharge. The large error of the 
individual months has a relatively small effect on the annual total, and 
it is for many purposes desirable to have the yearly discharge computed 
even though some error is involved in doing so. 

Accuracy and Reliability of Field Data and Comparative Results: 

Practically all discharge measurements made under fair conditions 
are well within 5 per cent of the true discharge at the time of observa- 
tion. Inasmuch as the errors of meter measurements are largely com- 
pensating, the mean rating curve, when well defined, is much more 
accurate than the individual measurements. Numerous tests and expe- 
riments have been made to test the accuracy of current-meter work. 
These show that it compares very favorably with the results from 
standard weirs, and, owing to simplicity of methods, usually gives results 
that are much more reliable than those from stations at dams, where 
uncertainty regarding the coefficient and complicated conditions of flow 
prevail. 

The work, of course, is dependent on the reliability of the observers. 
With relatively few exceptions, the observers perform their work hon- 
estly. Care is taken, however, to watch them closely and to inquire into 
any discrepancies. It is, of course, obvious that one gage reading a day 
does not always give the mean height for that day. As an almost 
invariable rule, however, errors from this source are compensating and 
virtually negligible in a period of one month, although a single day's 
reading may, when taken by itself, be considerably in error. 

In order to give engineers and others information regarding the 
probable accuracy of the computed results, footnotes are added to the 
tables of daily discharge and an accuracy column is inserted in the 
monthly discharge table. In the rating tables, "well deflned" indicates 
in general that the rating is probably accurate within 5 per cent ; "fairly 
well defined" within 10 per cent; "poorly defined" or "approximate," 
within 15 to 25 per cent. These notes are very general and are based 
on the plotting of the individual measurements with reference to the 
mean rating curve. 



20 

The accuracy column in the monthly-discharge table does not apply 
to the maximum or minimum nor to any individual day, but to the 
monthly mean. It is based on the accuracy of the rating, the probable 
reliability of the observer, and knowledge of local conditions. In this 
column, A indicates that the mean monthly flow is probably accurate 
within per cent; B, within 10 per cent; C, within 15 per cent; D, 
within-2o per cent. Special conditions are covered by footnotes. 

Use of the Data: 

It is the policy of the Internal Improvement Commission to make- 
available for the public the base data wdiich have been collected in the 
field by the Survey engineers, and these data will also be published in 
the Water Supply papers of the United States Geological Survey from 
time to time. This is done for the purpose of giving to any engineer 
the opportunity of examining the computed results and of changing 
and adjusting them as may seem best to him. Although it is believed 
that the rating tables and computed monthly discharges are as good as 
the base data up to and including the current year will warrant, it 
should always be borne in mind that the additional data collected at 
each station from year to year nearly always throw new light on data 
already collected and published, and hence allow more or less improve- 
ment in the computed results of earlier years. It is, therefore, expected 
that the engineer who makes serious use of the data given in these papers 
will verify all ratings and make such adjustments in earlier years as 
may seem necessary. 

The values in the table of monthly discharge are so arranged as to 
give only a general idea of the conditions of flow at the station, and it 
is not expected that they will be used for other than preliminary esti- 
mates. This is particularly true of the maximum and minimum figure, 
which, in the very nature of the method of collecting these data, are 
liable to large errors. The maximum value should be increased consider- 
ably for many stations in considering designs for spillways, and the 
minimum value should be considered for a group of, say, seven days 
and not for one day. 

The rating table, provided the engineer accepts it, is published pri- 
marily to allow him to apply it directly to the daily gage heights and 
rearrange the daily discharges in order of magnitude or by some other 
mctliod. ''I'lie ])recipitation and temperature tal)les in the appendix of

BIG MUDDY KIYER. 



Description. 

The drainage basin of the Big Muddy river lies in southern Illinois. 
The river rises in the northwestern part of Jefferson county, flows 
south to the town of Zeigler, in Franklin county, thence it flows westward 
to Murphysboro, in Jackson county, from there it flows south and empties 
into the Mississippi river about forty miles above Cairo, 111. Below 
Zeigler the river is extremely crooked. The length of the river is about 
100 miles, not including bends. The important tributaries are Beaucoup 
creek. Little Muddy river, Caseys creek and Middle Fork creek ; all these 
tributaries are small and of not much importance. The total drainage 
area is 2,320 square miles. 

The drainage basin is elliptical in shape with a major axis about 
seventy miles long and a minor axis about fifty miles long. The country 
is level or undulating; the soil is known as ^'.mulatto soil," a 3'ellowish- 
brown clay. Winter wheat is the staple crop. The southeastern part is 
underlaid with valuable coal veins and coal mining is carried on quite 
extensively. The slope of the river is small; its sources are about 710 
feet, and its mouth is about 310 feet above sea level. The banks and bed 
of the stream are soft and insecure. 

Til ere are no forested areas in this basin except occasional groves and 
tlie growth along the banks of the stream. 

Tlie mean annual rainfall is about forty-two inches. The winter 
conditions are mild; ice does not form very thick, and, as a rule, the 
snowfall is light and does not last long. 

Storage possibilities have not been investigated, but, owing to the 
growing demand for water in tliis section, they should receive careful 
attention. 

There are no opportunities for power development in this basin. The 
stream is similar to the other rivers in central and southern Illinois in 
that it is subject to high floods and very low water. In some localities 
llic high water overflows the land on each bank for two or three miles; 
some sections resemble a lake during floods. At Murphysboro, said to 
be sixty miles from the ]\Iississip])i following the river, there is frequently 
backwater, and floods reach the height of thirty feet above low water. 
Then^ is a possibility of constructing a canal from the Mississippi to 
the coal fields that lie along the Big Muddy. It is thought that only one 
lock would b(^ necessary. Canal construction would probably be very 
simple, as th(» country is low and the material to be excavated very soft. 



23 

The following gaging stations are being maintained in this basin : 
Big Muddy river at Cambon, 1908, 1909, 1910. 
Beauconp creek near Pinckneyville, 1908, 1909, 1910. 

Big Muddy River near Cambon, III. 

This station is located at the C, B. & Q. Railroad bridge, about one 
mile north of Cambon railroad station and about one and one-half miles 
east of Plumfield, 111. It was established June 16, 1908, for obtaining 
data for use in studying the problems of drainage, flood control and 
navigation, also to obtain general statistical and comparative data. 

The middle fork of the Big Muddy is tributary on the left bank 
about one-fourth mile above the station; the drainage area above the 
section is about 735 square miles. 

The datum of the gage has not been changed ; the records are reliable 
and accurate.

Beaucoup Creek ^EAll Pinckxeyville, III. 

This station is located at the I. C. Raikoad bridge, about one and 
one-half miles east of Pinckneyville, 111. It was established June 17, 
1908, for the purpose of obtaining data for use in studying drainage 
and flood control problems, and to obtain general statistical and com- 
parative data. „ , , , 1 XI 

Little Beaucoup creek is tributary on the left bank below the gaging 
station, and Galuin creek is tributary on the right bank about ten miles 
below the station. The drainage area above the section is about 227 

square miles. , n • -x • x n ^• 

The datum of the gage has remained unchanged since its installation. 
The records for 1908 were taken whenever the gage reader happened to 
be in the vicinity of the gage. Except in a few cases, fairly accurate 
results will be obtained if the missing gage heights are interpolated. 

The flood of 1902 reached a height of about 27.5 feet on the present 
o-aae • The creek goes dry at times; the water then stands in pools near 
the gage. ocffi •

EMBAKRAS ElVEK. 



Descriptiox. 

The drainage area of the Embarras river lies in the sontheastern por- 
tion of the State of Illinois. The river rises in the central part of 
Champaign count}:, near Frbana, flows in a southerly direction through 
Douglas, Coles and Cumberland counties to the center of Jasper county, 
whence it flows in a general southeasterly direction diagonally across 
Jasper county, the southwestern corner of Crawford county and thence 
across Lawrence county to its junction with the Wabash river about 
midway between Vincennes, Ind.-, and St. Francisville, 111. The river 
is extremely crooked, long tortuous bends being numerous; its length, 
exclusive of the bends, is about 125 miles. The most important tributary 
is Hickory creek or North Fork creek, which is tributary from the left 
bank about two and one-half imles below St. Marie, 111. The total 
drainage area is about 2,410 square miles. 

The drainage basin is long and narrow with a length of about 100 
miles and a fairly uniform width ranging from 15 to 30 miles. The 
surrounding country is level or gently rolling, with some small hills 
along the river. The sources of the river are about 730 feet and the 
mouth about 400 feet above sea level. In the lower portion of tho 
drainage basin in the vicinity of St. Marie the soil is sandy along the 
river, while to the north and west occurs the familiar black loam. To 
the east the soil is a light colored clay, Avhich was formerly covered with 
a heavy growth of "water oak.^' There has been very little drainage done 
in the uplands, but the bottoms are drained to some extent. 

There are extensive oil fields in the southwestern portion of the 
drainage basin west of Lawrence ville. In the upper portion of the 
drainage area, in the vicinity of Oakland, there is a sandy red soil near 
the river and black loam away from the river; one mile from the river 
on either side is prairie country. The chief crop in the drainage basin 
is corn, with some wheat. The overflow of the river does a large amount 
of damage and inundates large areas of bottom land throughout the 
entire length of the river. 

There are no forested areas in this drainage basin. The mean annual 
rainfall is about forty inches. The conditions during the winter period 
are mild, as a rule, with snowfall extending over a period of about two 
months and lasting only a few days at a time. Ice in the river averages 
three or four inches for about a month. The storage possibilities have 



42 

not been investigated. There are no opportunities for water power. 
There are no springs and little or no ground-water storage to keep up 
the low water flow, and in consequence there is little flow in the river 
during periods of extreme drought. During wet seasons the ground 
becomes saturated and heavy rains are carried to the river much- more 
rapidly than the stream can take care of and damaging floods result. 
Land drainage and flood control are subjects of considerable importance 
in this drainage area, and are being investigated at the present time. 

Two gaging stations have been established and are being maintained 
in this drainage basin: 

Embarras river near Oakland, 111., 1909, 1910. 

Embarras river at St. Marie, 111., 1909, 1910. 

Embarras Eiver near Oakland, III. 

This station is located at the highway bridge known as the "Antiocli 
Bridge," about two miles northwest of Oakland, 111., on the county-line 
road to Hindoboro and Areola. It was established Oct. 23, 1909, for 
the purpose of obtaining data for use in studying water supply, drainage 
and flood control problems, and also to obtain general statistical and 
comparative data. 

Brushy Fork creek is tributary from the left bank about five miles 
above the station. The total drainage area above the gaging station is 
.^oo square miles. 

The datum of the gage has remained unchanged since its installation ; 
tlie data are accurate and reliable. There was no flow at this station 
during a portion of the summer of 1908. The flood of 1897 reached a 
height of about twenty- four feet by the present gage datum.

EmBAKKAS KlVER NEAR St. MaIUE, IlL. 

This station is located at the highway bridge at the north end of 
Main street, St. Marie, 111., about 150 yards downstream from the 
C, H. & D. Eailroad bridge. It was established Oct. 20, 1909, for the 
purpose of obtaining data for use in studying problems of water supply, 
drainage, and flood control, and also to obtain general statistical and 
comparative data. 

Hickory creek, or Xorth Fork creek, is tributary from the left bank 
about two and one-half miles below the station. 

The total drainage area above the gaging station is about 1,540 square 
miles. 

The datum of the gage has remained unchanged since its installation ; 
the data are accurate and reliable. The flood of the spring of 1908 
reached a height of al)out 22.5 feet by the present gage datum.

any size; the most important are Shoal creek and Silver creek, which 
are tributary from the north at the lower part of the river. 

The drainage basin is long and comparatively narrow, the average 
width is about thirty miles, maximum width about sixty miles. The 
ground is low, level or undulating, and in consequence the slope of the 
river is small. The sources of the river are about 740 feet and its mouth 
about 350 feet above sea level. The soil is mostly black loam. In the 
lower portion of the drainage area the soil gradually changes to a 
yellowish-brown clay. Within twenty miles above Shelbyville occurs the 
only rock of any extent along this stream. In this fifteen or twenty- 
mile section the banks and bed are largely of limestone or sandstone, 
elsewhere the banks and bed are mostly soft soil with some gravel. 

There are no forested areas in this drainge basin; the annual rainfall 
is about forty inches. In general, the winter conditions are mild. 
Opportunities for storage have not been investigated to any extent, 
although it is a subject of considerable importance. There are no oppor- 
tunities for water power development of any importance anywhere along 
the river. Owing to the lowness of the drainage area there is little 
opportunity for ground-water storage. During wet weather the ground- 
water plane rises to the surface of the ground and the rains run off 
into the streams very quickly, producing very sudden rises and floods. 
During dry weather, since there is little or no ground-water stored, the 
flow of the stream becomes very small and in some places dries up 
entirely. The banks of the river are low and in times of floods large 
areas are covered with water, delaying the planting of crops and some- 
times destroying growing crops. Storage possibilities, land drainage and 
flood control are matters of considerable importance in this basin.

The following gaging stations have been established and maintained 
in this drainage basin : 

Kaskaskia river near Areola, 1908, 1909, 1910. 
Kaskaskia at Shelbvville, 1908, 1909, 1910. 
Kaskaskia at Vandalia, 1908, 1909, 1910. 
Kaskaskia at Carlvle, 1908, 1909, 1910. 
Kaskaskia at Xew Athens, 1909, 1910. 
Shoal creek near Breese, 1909, 1910. 
Silver creek near Lebanon, 1908, 1909, 1910. 

Kaskaskia Eiver near Akcola, III. 

This station is located at the highway bridge known as the Bagdad 
bridge, about four miles west of Areola, 111. It was established April 
11, 1908, for the purpose of obtaining data for use in studying drainage, 
flood protection, and storage problems, and also to obtain general statis- 
tical and comparative data. 

Lake Fork is tributary from the west about three or four miles above 
the gaging station. The drainage area above the station is about 390 
square miles. 

The datum of the gage has remained unchanged since its installation, 
and the records are accurate and reliable. 

The river at this point is said to go dry at times and .was dry for about 
two months in 1908. The highwater of May, 1908, reached a height of 
17.3 feet on the gage.

Kaskaskia Kiver at Shelbyville, III. 

This station is located at the highway bridge at the edge of Shelbyville, 
just above the C. & E. I. and Big Four Railroad bridges and just below 
the pumping station of the City Water Company of Shelbyville. It was 
established Feb. 25, 1908, for the purpose of collecting data for use in 
studying drainage and flood control problems, and to obtain general 
statistical and comparative data. 

There are no tributaries of any size entering the stream near Shelby- 
ville. The drainage area above the gaging station is about 1,030 square 
miles. 

The datum of the gage has remained unchanged since its installation. 
The gage heights may be affected during high water by backwater caused 
by the lodging of drift at the two railroad bridges below the gaging 
station. The records are accurate and reliable.

Kaskaskia Eiver at Vandalia, III. 

This station is located at the highway bridge at the east end of Main 
street, Vandalia, 111. It was established Feb. 26, 1908, to obtain data 
for use in studying drainage questions, flood protection, levee construc- 
tion, and for general statistical and comparative purposes. No tribu- 
taries of any size enter the river near Vandalia. The drainage area 
above this point is about 1,980 square miles. 

The river for some miles above and below Vandalia is leveed along 
the left bank. It is claimed that these levees, by confining the floods, 
have caused floods of unusual height on the right side of the river, and a 
number of law suits have been instituted to recover damages to property 
situated on the right bank. During extreme floods these levees some- 
times give way, thus reducing the flood flow; all the water, however, 
eventually passes the gaging section. 



74 

The datum of the gage has remained unchanged since its installation. 
The records are reliable and accurate.

discharge measurements made during 1908-1910 and is well defined between gage heights 2.3 feet and 
14.0 feet. Above gage height 15.5 feet the rating curve is tangent, the difference being 50 per tenth.

KasKA.sk 1 A IklVKU AT C'AKLYLE, IlL. 

This station is located at the B. & 0. S. W. Kailroad bridge, about 
one-fourth mile east of the railroad station at Carlyle, 111. It was 
established March 2, 1908, for the purpose of obtaining data for use in 
studying drainage, flood control, and water supply problems, and to 
obtain general statistical and comparative data. 

'J'hcrc are no tributaries of any size for ten miles above and below 
this station. Shoal creek is tributary on the right bank about fifteen 
miles below the station. 'J'he drainage area above the gaging station is 
about 2,680 square miles. 

The intake of the water sup])ly system of Carlyle is above the gaging 
station. There is a dam a)H)ut lU/o ^^^'t high about 700 feet above the 
section which is used for water supply purposes. The average amount 
of water pumped is about .3,r)0(),(l0() gallons every thirty days, and during 
.Iiitic. .Inly and August the (pianlity is about 4,500,000 gallons every 



83 

thirty days. The outfalls of one section of the city sewerage system 
and some private sewers are above the gaging station, so the diversion 
is small. 

The datum of the gage lias remained unchanged since its installation; 
the records are accurate and reliable. The flood of 1882, which is the 
highest known, is said to have reached a height of 1% feet higher 
than the- flood of 1908, or about 321/2 feet on the present gage. The 
stream never goes dry at this point. It has been noticed during periods 
of low water that the water is hard, which fact indicates that the flow 
is kept up by springs.

Kaskaskia IUvek at Xew Athens^ III. 

This station is located at the I. C. Eailroad bridge, about 600 feet 
north of the I. C. Eailroad station at New Athens, 111., and about 600 
feet upstream from the highway bridge. It was established Nov. 1, 
1909, for the purpose of obtaining data for use in studying problems 
of drainage, flood control, and navigation, and to obtain general statis- 
tical and comparative data. 

Silver creek is tributary on the right bank about one mile above, and 
Lively creek is tributary on the left bank about three miles below the 
gaging section. The total drainage area above the gaging station is 
about 5,220 square miles. 

The datum of the gage has remained unchanged since its installation, 
and the records are accurate and reliable. The stream is fed by springs 
and never goes dry at this point. The flood of the fall of 1S08 reached 
a height of about 34.5 feet on the present gage datum. 



92 

A record of river height at this point from Jan. 23^ 1907, to Oct. 28, 
1909, inclusive, was kept for the Xew Athens Journal by C. J. Von Roth 
Roffy. The river height was taken on Wednesday and Thursday morn- 
ings of each week, the river height for Thursday being published each 
Friday with the change in twenty-four hours as obtained from the river 
height of Wednesday. This record of stage was kept by the Journal 
mainly for the information of farmers living on the west side of the 
river, who are cut off from reaching New Athens via the highway bridge 
when the river reaches a stage about thirty feet. The record is authentic. 
These gage heights have been carefully reduced to the datum of the 
present gage, the maximum error is probably not over 0.4 feet., the

SiroAL Creek near Breese, 111. 

This station is located at the B. & 0. S. W. Eailroad bridge, about 
one and one-half miles east of Bj'oese, 111. It was established Nov. 5, 
1909, for the purpose of obtaining- data for use in studying problems 
of drainage, flood control, water supply, and storage, and also to obtain 
general statistical and comparative data. 

Beaver creek is tributary on the left bank about three miles below 
the section. The total drainage area above the gaging station is about 
760 square miles. The intake of the pumping station of the water 
supply system of Breese is about one-fourth mile q,bove the gaging 
section. 

The datum of the gage has remained unchanged since its installation; 
the records are accurate and reliable. The creek is fed by springs and 
has not been known to go dry at this point. The flood of 1907 reached 
a height of al)out twenty-two feet on the present gage datum.

Silver Creek near Lebaxox, III. 

This station is located at the highway bridge at Wrights Crossing, 
about two miles west of Lebanon, 111., between the B. & 0. S. W. Rail- 
road and the East St. Louis & Suburban Railway liridges across Silver 
creek. It was established March 3, 1908, for the purpose of colkK-ting 
data for use in studying drainage and flood control ])roblenis. and to 
obtain general statistical and comparative data. 

There are no tributaries near the gaging station. This stream is a 
tributary of the Kaskaskia river, emptying into it about one mile above 
the gaging station at Xew Athens, 111. Tbe drainage area above the 
station is about 335 square miles. 

The datum of the gage has remained unchanged since its installation. 
From March 3, 1908, to May 10, 1909, this gage was so situated that 
two feet was the lowest obtainable reading, and the gage reader noted 
that the stream was dry whenever the water surface was below two feet. 
Upon inquiry he stated that the stream was dry only one week during 
1908. Therefore, where gage heights have been niarked ''Dry" by the 
gage reader during this period, this note was inserted : , "Dry under 
gage, can not obtain gage height of water surface." The position of 
the gage was changed on May 10, 1909, so as to obviate this difficulty. 
Except as noted above the records are accurate and reliable.

LITTLE WABASH EIYEE. 



Skillet Fokk River near Wayxe City, III. 

This station is located at the Southern Eailwav bridge, al)oiit one 
mile east of Wayne City, 111. It was established Aug. Td, 1908, for 
the purpose of obtaining data for use in studying problems of drainage 
and flood control, and also to obtain general statistical and comparative 
data. 

Horse creek is tributary on the right bank about four miles above 
the section. The drainage area above the gaging section is about 481 
square miles. 

The gage datum has remained unchanged since its installation and 
the records are accurate and reliable. 

. On :\Iarch 11, 1909, the water reached a height of 22.8 feet on the 
gage.

SANGAMON EIVEE. 



Description. 

The drainage basin of the Sangamon river lies wholly within the 
State of Illinois. The river rises in the southwestern part of Ford 
county, flows southwest to Decatur in Macon county, thence flows west- 
ward until near Springfleld, thence it flows northwestward to its junc- 
tion with Salt creek at the northern boundary line of Menard county, 
thence it flows westward and empties into the Illinois river at the 
northern boundary of Cass county. Springfield is about twenty miles 
southwest of the center of the basin, which is roughly a right triangle 
in shape, with the mouth of the river opposite the vertical ; the drainage 
basin lies very nearly in the center of the State. The river is about 
180 miles in length, not including bends. The total drainage area is 
5,410 square miles. The principal tributaries are Salt creek and South 
fork. 

The eastern third of the drainage basin is somewhat undulating and 
elevated, the rest of the basin is a level prairie. The soil is a very 
fertile rich black loam, especially adapted for raising corn. There are 
coal mines in the vicinity of Springfield. The bed and banks of the 
river are soft and insecure. The slope of the river is small, the elevation 
of its source is about 700 feet above sea level, its mouth is about 430 
feet. There are no forested areas in this drainage basin; what little 
timl)er there is is in small groves or along the river banks. 

'J1ie annual rainfall is about 37 inches. The winter conditions are 
mild; ice forms to some extent and during severe winters attains con- 
siderable thickness. 

Storage possibilities have not been investigated, although, as in the 
Kaskaskia basin, storage is of considerable interest. 

On account of the low slope, floods, low water and lack of suitable 
foundations for dams, there are no opj)ortunities for water power. 

Owing to the levelness and lowness of the drainage area there is very 
little ground storage in the basin; high water follows every heavy rain, 
floods occur frequently and are of considerable duration. The banks 
of the river being low, large areas are flooded and there are numerous 
swamp areas in this basin. The drainage of these swamps and the 
opening up of channels so that flood waters may have an opportunity 
of returning quickly to the main stream makes the study of flood 
control and drainage of considerable importance. In some places short 



129 

sections of the main stream are being straightened in an effort to 
provide a better channel so that floods will quickly drain off the 
adjacent land. Any improvement of this nature should tonsider tlie 
stream as a whole and shouid be commenced at the lower end. 

The foliowing gaging stations are being maintained in this drainage 
basin : 

Sano^amon river near Monticello, 1908, 1909, 1910. 

Sangamon river at Eiverton, 1908, 1909, 1910. 

Sangamon river near Oalvford, 1909, 1910. . 

Sangamon river near Chandlerville, 1908. 
. South forlv near Tavlorville, 1908, 1909, 1910. 

Salt creels' near Kenney, 1908, 1909, 1910. 

SaxGAMOX ElVER XEAR MOXTICELLO, IlL. 

This station is located at the I. C. Eailroad bridge, about one-half 
mile west of Monticello, 111. It was established Feb. 4, 1908, for the 
purpose of collecting data to be used in studying drainage, water 
supply, and flood control problems; and also for obtaining general 
statistical and comparative data. 

There are no tributaries of any size near this station; the drainage 
area above the section is about 550 square miles. 

The datum of the gage has not been changed ; the records are reliable 
and accurate.

Sangamon River at Eiverton, III. 

This station is located on the Wabash Railroad bridge, about one- 
fourth mile west of the depot at Riverton, 111. It was established 
Feb. 13, 1908, to obtain data to be used in the study of drainage and 
flood control prol)lenis, and also to obtain general statistical and com- 
parative data. 

The Soutli fork is tributary two or thr(H3 miles al)ove the station : the 
drainage area above the section is al)out 2,500 square miles. 

The datum of the gage has not been cluinged ; the records are reliable 
and accurate. 

The high water of 1883 reached a height of a])proximately ;>2 feet 
on the present gage. The high water of 1875 is said to liave l)een 
about one-half foot lower than tlie flood of 1883.

Saxgamox Eiver xear Oakford, III. 

This station is located at the highway bridge about three miles north- 
east of Oakford, 111., and about two and one-half miles np-stream from 
the C, P. & St. L. Eailroad bridge. It was established Oct. 26, 1909, 
for the purpose of obtaining data for use in studying problems of 
drainage and flood control, and to obtain general statistical and com- 
parative data. 

Crane creek is tributary on the right bank about one and one-fourth- 
miles below, and Salt creek is tributary on the right bank about six 
and one-fourth miles above the section. The total drainage area above 
the gaging station is about 5,000 square miles. 

This station is on the improved portion of the river, the new channel 
being straight for about five miles above and one and one-half miles 
below the gaging section. This artificial channel was constructed TO 

—10 s w 



14G 

feet wide at the top and is now about 140 feet wide, so that material 
changes are liable to occur in the gaging section, tending to cause a 
variation in the relation of discharge to gage height. The C, P. & 
St. L. Bailroad bridge, two and one-half miles below the section, is a 
wooden trestle with numerous piles in the stream bed which have a 
decided tendency to obstruct the flow at high water, as the trestle is at 
an angle to the current. Drift and ice lodge at this trestle and affect 
the gage heights. 

The datum of the gage has remained unchanged since its installation. 
Because of the inaccessibility of the gage it has not been possible to 
obtain daily readings, but the records obtained are accurate and reliable. 

The floods of February and March, 1907, and May, 1908, reached 
a height of about 21 feet on the present gage datum.

Salt Creek xeak Kexxey, III. 

This station is located at the highway bridge, about three miles west 
of Kenney, 111., a short distance below the Yandalia Kailroad bridge. It 
was established Feb. 14, 1908, in order to collect data to be used in the 
study of drainage and flood control problems, and to obtain data for 
general statistical aud comparative ])urposes. 

Ten Mile creek is tributary on the right bank about four miles above 
the gaging station. Salt creek is a tributary of the Sangamon river. 
The drainage area above the section is about 459 square miles. 

The datum of the gage has not been changed ; the records are reliable 
and accurate. 

The high water of 1882 is said to have been about one or one and 
ouo-half feet higher than that of tlie spring of 1908, or to have reached 
a hciglit of about sixteen feet 'on tlie present gage.

SouTJt Fork of Sangamon Kiveii near Taylorville, 111. 

This station is located at the Wabash Kailroad bridge, about three 
and one-half miles southwest of Taylorville, 111., and about one-fourth 
mile up-stream from the highway bridge across the South fork known 
as the ''Half Acre Bridge." It was established Feb. 11, 1908, for the 
purpose of obtaining data for use in studying drainage, flood control, 
and water supply problems, and also to obtain general statistical and 
comparative data. 

Bear creek, a small tributary, enters the stream on the left bank a 
few miles below the station. The drainage area above the gaging station 
is about 427 square miles. 

In August, 1909, a drainage ditch was dug along the river in this 
vicinit}', straightening the course of the stream, but coinciding with the 
original channel at the gaging station. The cross-section of the stream 
at the gaging station was not altered, but the relation between gage 
height and discharge was materially changed, due to the change in 
slope. The gage heights to Aug. 10, 1909, inclusive, refer to the section 
before the change. The gage heights from Aug. 11 to Sept. 1, 1909, 
inclusive, are of no value, because the stream was dammed up for purpose 
of construction during that period. On Sept. 2, 1909, the datum of 
the gage was lowered two feet, and the gage heights from that date on 
refer to the new conditions. In all comparisons between the data for 
the original and the new conditions it should be noted that the gage 
datum has been changed. The records are accurate and reliable.

CAHOKIA CKEEK. 



Description. 

The drainage area of Cahokia creek lies in the southwestern part of 
the State of Illinois. The creek rises in the southern part of, and about 
on line between Montgomery and Macoupin counties, flows in a south- 
westerly direction diagonally across the southeast corner of Macoupin 
county and the northwest portion of Madison county, past Edwardsville, 
through East St. Louis, 111., and empties into the Mississippi river. The 
creek is very crooked and its length is approximately fifty-five miles. 
The total drainage area is 375 square miles. Its principal tributary is 
Indian creek, which enters from the right bank about three-fourths 
of a mile north of the Wabash Eailroad bridge near Poag, 111. 

The drainage basin is long and narrow, being about forty-five miles 
in length ; the average width is about eight miles; and maximum width 
is about twelve miles. The ground is low, level, or undulating, with a 
cliain of bluffs crossing the drainage area just north of Poag. 111. The 
sources of the creek are about 680 feet, and the mouth about 385 feet 
above sea level. 

There are no forested areas in this drainage basin. The mean annual 
rainfall is about forty inches. In general, the winter conditions are 
mild. The opportunities for storage and water power development have 
not been investigated, but are undoubtedly not worthy of consideration. 
Flood control, especially in its relation to the proposed flood protection 
works of the East Side Levee and Sanitary District of East St. Louis, 
111., is the most important problem under consideration at present in 
connection with this drainage basin. 

One gagins: station has been maintained in this drainage basin : 

Cahokia creek near Poag, 111., 1909, 1910. 

CAiroKiA Creek near Poag, III. 

This station is located at the Wabash Railroad bridge, about three- 
fourths of a mile northeast of the Wabash Railroad station at Poag, 111. 
It was established Dec. 13, 1909, to obtain data for use in studying 
drainage and flood control problems. The data collected will bo used 
by the East Side Levee and Sanitary District of East St. Louis, TIL, in 
its study of flood control and preveuiion at that place. 



172 



Indian creek is tributary from the right bank about three-fourths of 
a mile above the section. The total drainage area above the gaging 
station is 259 square miles, as determined by the East Side Levee and 
Sanitary District. 

The datum of the gage has remained unchanged since its installation ; 
the records are accurate and reliable. The data at present are insufficient 
for a determination of the dailv flow.

LITTLE WABASH EIVEE. 



E'ESCRIPTIOX. 

The drainage basin of the Little Wabash river lies in the southeastern 
part of the State of Illinois. The river rises in the southwestern corner 
of Coles county, flows slightly southeastward and empties into the Wabash 
river, about fifteen miles above its mouth, at the boundary line between 
White and Gallatin counties. The Skillet fork is the only tributary of 
any size, joining it not far from its mouth. The Little Wabash is about 
150 miles in length. The total drainage area is 3,200 square miles. 

The basin is shaped something like a parallelogram with the long sides 
north and south. The country is level or undulating. The soil is a 
rich black loam in the northern part; in the southern part it gradually 
changes into a yellow clay or '^mulatto soil." The elevation of the 
sources of the river is about 720 feet; at" its mouth it is about 340 feet 
above sea level. There are no forested areas in this basin. The annual 
rainfall is about forty-two inches. The winter conditions are mild ; ice 
does not form very thick, snowfall is light and does not last long. 

Storage possibilities have not been investigated, although the growing 
demand for water and for flood control makes storage a subject of con- 
siderable importance. 

There are no opportunities for water power development anywhere in 
this basin. 

Drainage and flood control are subjects of considerable interest along 
this river. The LTnited States Department of Agriculture is making 
a study of conditions with a view of developing a plan for reclaiming 
and protecting areas that are overflowed during floods. Portions of the 
river have already been mapped for use in this study. 

The following gaging stations are being maintained in this basin : 

Little Wabash river near Clay City, 1908, 1909, 1910. 

Little Wabash river near Golden Gate, 1908, 1909, 1910. 

Little Wabash at Canni, 1908, 1909, 1910. 

Skillet fork near Wayne City, 1908, 1909, 1910. 

Skillet fork near Mill Shoals, 1908, 1909, 1910.

Little Wabash Kiver xear Clay City, III. 

This station is located at the B. & 0. S. W. Eailroad bridge, about 
two miles east of Clay City, 111. It was established Oct. 3, 1908, for 
the purpose of obtaining data for use in studying problems of drainage 
and flood control. 

Big Muddy creek is tributary from the left bank about five miles 
below the section. The total drainage area above the gaging station is 
about 808 square miles. 

This station is at the toe of a horseshoe bend in the river and thsf 
ground inside the bend along the railroad track is low. During high 
water the Little Wabash river overflows into Little Muddy creek, a 
brancli of Big Muddy creek, and in extreme high water also overflows 
into Big Muddy creek, forming at such times a sheet of water about 
four miles in wddth along the railroad embankment. The discharge of 
the Little Wabash at the gaging station during extreme high water can 
not be determined on account of the above conditions, for the flow which 
passes the gaging station includes some of the flood waters of Big 
Muddy creek. 

The datum of the gage has remained unchanged since its installation, 
and the records are reliable and accurate. 

Springs feed the river near the gaging station and the river has not 
been known to go dry at this point. The flood of Feb. 8, 1909, reached 
a height of 23.7 feet on the gage. This station is maintained principally 
to determine the height of high water and the duration of floods. On 
account of insufficient data and poor condititDns at the section, the daily 
discharge could not be determined.

Gage heights May 15 and June 25 were obtained by interpolation. 



Little Wabash Eiver near Golden" Gate, III. 

This station is located at the Southern Eailroad bridge, about one 
mile west of Golden Gate, 111. It was established Aug. 17, 1908, for 
the purpose of collecting data for use in drainage and flood control 
investigations. 

Elm creek is tributary from the right bank about one mile above the 
station. The total drainage area above the gaging section is about 1,780 
square miles. 

The datum of the gage has not been changed since its installation, and 
the records are accurate and reliable. 

The stream does not go dry at this point. This station is affected by 
backwater from the Wabash river. Therefore, the relationship between 
gage heights and discharge is variable and hence daily discharges could 
not be determined from the data at present available.

Gage heights Jan. 1-12 were affected by ice conditions. 



Little Wabash Eiver at Carmi, III. 

This station is located at the highway bridge in the northeastern part 
of Carmi, 111., about one-fourth mile below the Big Four and L. & N. 
Eailroad bridge. It was established Oct. 9, 1908, to obtain data for 
use in studying drainage, flood control and levee construction. 

Skillet Fork river is tributary on the right bank about four and one- 
half miles above the station. The drainage area above the gaging section 
is about 3,090 square miles. 

The relation between discharge and gage height at this station is 
affected by backwater from the Wabash and Ohio rivers, especially during 
extreme floods. 

The datum of the gage has remained unchanged since its installation. 
The records are accurate and reliable, but are affected by backwater, as 
stated above. 

The following high water marks liave been preserved at this station : 
1875, gage height 33.5 feet; about 1895, gage height 34 feet; 1897, gage 



184 

height 34.0 feet; and 1898, gage height 36 feet; all based on present gage 
datum. These high water records are accurate and authentic. There is 
some possibility that the dates may be slightly in error. 

On account of l)ackwater conditions at this station the daily discharge 
cannot be determined with the data at present available.

This station is located at the B. & 0. Eailroad bridge, about one mile 
south of Mill Shoals, 111. It was established Oct. 9, 1908, for the 
purpose of obtaining data for use in studying drainage and flood control 
])roblenis. 

Grifhn creek is tributar}- on the left bank about one and one-half 
miles above the station, and Haw creek is tributary on the right bank 
about five miles above the station. The drainage area above the ^aoinff 
.section IS about 912 square miles. ^ o & 

Tlic datum of the gage has remained unchanged since its installation, 
and the records are accurate and reliable. 

This station is affected by backwater caused by floods on the Wabash 
river. Sufficient data are not available at present to enable* the daily 
discliarge to be determined.
